Hayabusa Pistons question..

[ApocWarrior]

Any information is appreciated.

Picked up some 2000 Hayabusa pistons and rods.

My question is actually ring related, since the Hayabusa was a chrome bore and my Bandit iron . Can the Busa rings be used?

I'm suspecting I would have to buy a specific ring for that.

Any input of how much more boost I can run afterwards?

Currently at around 8psi.

Ive never bothered changing rings, never had any problems in over 20k miles.

Run 15psi regularly and up to 17psi for landspeed stuff. Again never had any problems

I have just used the rings that came with the busa pistons on the 3 Turbo motors I have built with no problems, am also running 15psi.

No issues myself nipped a piston but rings had no issues

Chrome bores just reduce drag

Big thanks. That's just good news to me. I've got another low miles 1200 motor about to tear down.

And wear, chrome being harder than steel.

All true if they were actually chrome bores . . . . . which they aren't! The Busa block is all aluminium, no steel liners, and uses Nikasil coating - Nickel Silicon Carbide, harder than Chrome and plated onto Aluminium allows tighter piston to bore clearances and better heat transfer.

EDIT : Suzuki actually use a patented coating SCEM ( Suzuki Composite Electro-Chemical Material) which uses Nickel Phosphorus Silicon Carbide.

Yes indeed there are nikasil but I was splitting his balls over calling them chrome

And the biggest reason it was used , was to reduce engine width and weight.

+1 on std busa rings and 15 psi, no issues yet after 2.5k road miles

re : the above last point, considering the advanced / newer design, they 'almost' succeeded - they are a f**kin' heavy chunk, not quite GSX heavy but certainly GSXR 1100 LOL!
